Coronaviruses (CoV), are a large family of viruses that cause diseases ranging from mild to cold more serious diseases, such as respiratory syndrome in the Middle East (MERS-CoV)and severe acute respiratory syndrome (SARS-CoV). Currently, new coronaviruses are emerging in China (nCoV). It is a strain that has not been previously identified in humans.
Coronaviruses are zoonoses, which means they are transmitted between animals and humans. Detailed investigations have found that SARS-CoV and MERS-CoV are transmitted from animals to humans. Several known coronaviruses circulate only in animals and have not yet passed on to humans.
Signs of infection include respiratory symptoms, fever, coughing, and difficulty breathing. In more severe cases, the infection can cause pneumonia, a severe acute respiratory syndrome, kidney failure and even death.
Standard recommendations to prevent the spread of infection include regular hand washing, covering the mouth and nose when coughing and sneezing, thorough cooking of meat and eggs. Avoid close contact with anyone showing symptoms of respiratory illnesses such as coughing and sneezing.
How is coronavirus transmitted?
The new coronavirus is an airborne respiratory virus. This means that the infection is effected by drops / aerosols, which are released into the air by the sick person during sneezing, coughing and talking and are inhaled by another person. Therefore, it is important to observe very good hygiene – use of masks, sneezes and coughs in the elbow / sleeve fold, frequent hand washing and disinfection.
If sprays containing the virus fall on surfaces or are spread over their hands, someone else can become infected by touching those surfaces and then their face (eyes, mouth, nose). Door handles, elevator knobs, stair railing, public transport catchment areas are examples of surfaces that can be contaminated. It is not yet clear how long the virus can live on these surfaces – whether for hours or days, but it is best to avoid touching them and washing their hands frequently.
Will spraying the body with alcoholic solutions and bleach destroy the coronaviruses?
The use of disinfectant surface solutions on the body cannot affect the virus that has already invaded the body. At the same time, these solutions can damage the skin, mucous membranes of your eyes or your clothes, so it is not recommended to use them on your body.
Do climate and temperature affect the spread of coronavirus?
It is not yet known whether seasonal temperature changes affect the spread of the virus as opposed to viruses such as influenza.
Along with washing hands and avoiding touching surfaces in public, the use of a n65 mask is one of the most effective means of protection.
